Find out what ecu/computer you have... that is the question that matters.
If you want direct control of timing and fuel based on BOOST, then the tweecer isn't the right choice.
The tweecer does allow you to change any factory parameter/setting though... and there are plenty of guys running a tweecer with boost VERY successfully.
Also, look into the Moates QuarterHorse, as it has surpassed the capabilities of the tweecer.
